Title: Improvements in or relating to the manufacture of hollow articles from thermoplasticmaterials
Inventor: WHITBOURN KENNETH JOSEPH
IPC: B29C49/50
Filed: 1959-12-21
Abstract: 929,633. Removing sprue from blown hollow articles. METAL BOX CO. Ltd. Nov. 16, 1960 [Dec. 21, 1959], No. 43366/59. Class 87(2). In a method of removing sprue from both ends of a hollow article made by a known process in which a tube of plastic material is extruded over a hollow mandrel and surrounded by a closed sectional mould, so that the tube is pinched at one end and pressed against the mandrel at the other end, the tube then being blown inside the mould, the sprue is automatically removed while the article is at least partly contained in the mould. In Fig. 8, a bottle 35 has been blown on a mandrel 14 in the mould halves 1. 2. The neck sprue 17 is removed by means of a stripper element 24 mounted on bars 25, Figs. 8 and 10, the element being normally held against the surface of the mould section 1 by springs 26, so that it lies flush with the edge 27, Fig. 8, of the mould. The mould part 2 is fitted with latches 29 pivoted at 33 and pulled inwardly by springs 30. On closing the mould the latches 29 pass through slots 31 in the stripper element 24 and then are engaged behind the element. When the mould is opened the latches 29 cause the stripper element 24 to move with the mould part 2 and so remove the sprue 17 from the bottle neck, until the cams 32 release the latches 29 and the element 24 returns to its normal position. To facilitate removal of the neck sprue 17 the mould halves are provided with circumferential cutters 36, which engage with the mandrel 14 and weaken the tube at the neck when the mould is closed. The cutter 36 is also provided with a secondary cutter parallel to the axis of the mandrel to enable the sprue to split more easily on removal. Fig. 5 is a plan view of the top of the mould 1, 2 showing the sprue 16 formed at the bottom of the bottle. This is removed by a member 18 reciprocated by a double-acting air cylinder 19 and piston rod 20, and guided by fixed guides 21. The air is applied to cylinder 19 before the mould opens, when the member 18 is restrained from movement by stops 23, so that the pressure builds up. As the mould opens the member 18 flies across the top of the mould removing the sprue 16. The stops 23 are not essential but they ensure that the sprue is impelled clear of the mould. Specification 929,634 is referred to.

Title: Waveguide switch apparatus
IPC: G01S7/03
Filed: 1959-12-22
Abstract: 862,741. Waveguide impedances and switches. MICROWAVE ASSOCIATES Inc. Dec. 22, 1959 [Dec. 29, 1958], No. 43524/59. Class 40(8) A waveguide switch comprises a rotatable conductive vane 23 mounted in a waveguide section 8 of uniform cross-section, the vane being rotatable from a position transverse to the axis of the guide to a position parallel to the axis. The vane is mounted in ball-bearings 16, 21 and is biased to either the open or the closed position by means of a coil spring 37. In the open (parallel) position, the capacitance presented by the vane is compensated by metallic bosses 24, 26 arranged at the ends of the axis of the vane. It is actuated by means of a short bar magnet 32 attached to the end of shaft 28. The magnet lies in the air gap of a magnetic circuit comprising a pair of cored solenoids 46.1, 46.2, a pair of pole pieces 49, 51 and a magnetic yoke 42, all these elements being accommodated in the annular space between the flanges (not shown) of the waveguide section. The extreme positions of the vane are determined by a stop 36 which coacts with the bar magnet. The vane 23 does not touch the broad sides of the waveguide section 8 so that in the closed (transverse) position the guide is shunted by a capacitance. This capacitance may be tuned out by means of a rectangular inductive iris (not shown) formed in the vane. Alternatively, inductance may be provided by means of two conductive plates arranged parallel to the vanes near its shorter edges. Instead of tuning out the capacitance, measures may be taken to reduce it, e.g. the long edges of the vane may be provided with slots filled with dielectric material or a dielectric-filled slot may extend completely through the vane. The switch may be electrically coupled to a TR tube in such a manner that it is opened and closed as the keep-alive potential is switched on and off.

Abstract: 958,982. Packaging-machines. G. ROSSI. Dec. 12, 1961 [Dec. 31, 1960], No. 44400/61. Heading B8C. Sealed packages are formed under vacuum by inserting a container of pliable heat-weldable material into a receptacle 8, filling the container with the material to be packaged, raising the receptacle 8 by means of a pneumatic cylinder 6 against an opening in a vacuum chamber 10, in which chamber the container is heat-sealed under vacuum produced by a suction pump 33. The container is moulded according to the interior shape of the receptacle 8, e.g. to a parallelopipedic cylindrical or prismatic shape, by the pressure of its contents. The receptacle 8 is then placed on a vertically reciprocable plate 7, the mouth of the container projecting from the receptacle. The operator causes the plate 7 to be raised, and vacuum to be created in the chamber 10. At a predetermined pressure a gauge 42 operates an electric valve 35 to move a pneumatic piston 27, thereby operating one of a pair of sealing jaws in the chamber 10. In closing, the jaws operate a micro-switch 12, time switch 41 and thereby an electro-pneumatic valve 31 controlling the air pressure in the, chamber 10. The contact of pressure gauge 42 is opened to displace the piston 27 to the right as seen in Fig. 1, and .thereby open the sealing jaws. On the appearance of a shaft 50 on the piston 27, the operator causes the plate 7 to be lowered.
